2012-05-09 Ramana Radhakrishnan <ramana.radhakrishnan@linaro.org>
* tree-ssa-loop-ivopts.c (add_autoinc_candidates, get_address_cost):
Replace use of HAVE_{POST/PRE}_{INCREMENT/DECREMENT} with
USE_{LOAD/STORE}_{PRE/POST}_{INCREMENT/DECREMENT} appropriately.
* config/arm/arm.h (ARM_AUTOINC_VALID_FOR_MODE_P): New.
(USE_LOAD_POST_INCREMENT): Define.
(USE_LOAD_PRE_INCREMENT): Define.
(USE_LOAD_POST_DECREMENT): Define.
(USE_LOAD_PRE_DECREMENT): Define.
(USE_STORE_PRE_DECREMENT): Define.
(USE_STORE_PRE_INCREMENT): Define.
(USE_STORE_POST_DECREMENT): Define.
(USE_STORE_POST_INCREMENT): Define.
(arm_auto_incmodes): Add enumeration.
* config/arm/arm-protos.h (arm_autoinc_modes_ok_p): Declare.
* config/arm/arm.c (arm_autoinc_modes_ok_p): Define.
